ABSTRACT

APPARATUS FOR CONVEYING ROLLS OF PHOTOGRAPHIC FILM OR PAPER BETWEEN A FIRST STATION (SUCH AS A SLITTER S) AND A SECOND STATION (SUCH AS A STORAGE AREA) COMPRISES TWO IDENTICAL LOADING OR UNLOADING SUBSTATIONS S1 AND S2, AND SEPARATE CARRIAGES C1 AND C2 HAVING BALL CASTERS RUNNING IN GROOVED TRACKS FOR ENGAGING ROLLS R1 AND R2 AND CARRYING THEM TO SLITTER S. THE TRACKS COMPRISE A SINGLE PAIR 55, 57 ADJACENT TO AND CENTERED ON THE SLITTER, AND EXTENDING LATERALLY IN OPPOSITE DIRECTIONS THEREFROM; AND TWO OTHER PAIRS 47, 51 AND 69, 71 EXTENDING TO SUBSTATIONS S1 AND S2 AT RIGHT ANGLES FROM, AND CONNECTING SMOOTHLY TO, OPPOSITE ENDS OF TRACKS 55, 57. CARRIAGE C2 IS U-SHAPED AND ENCLOSES A HYDRAULIC ELEVATOR E2 ON THREE SIDES, UPON   WHICH A DOLLY CARRYING A BOXED ROLL IS RUN AND IS THEN LIFTED UP SO THAT GUDGEONS 11, 13 ENGAGE THE ENDS OF THE ROLL. GUDGEONS 11 AND 13 ARE MOVABLE TOWARD AND AWAY FROM ONE ANOTHER. LEVELLING JACKS 31 ON ELEVATOR E2 PROVIDE FINE POSITIONING OF THE BOX B AND THE ROLL R2. THEN THE ELEVATOR IS LOWERED SO THAT BOX B AND DOLLY D CAN BE ROLLED OFF THE ELEVATOR. EACH CARRIAGE IS PROVIDED WITH A DOWNWARDLY EXTENDING GUIDE WHEEL WHICH ENGAGES A CAM SURFACE 67 ADJACENT SLITTER S TO KEEP THE CARRIAGE ROLLING IN A STRAIGHT LINE.
